PORTABLE AND FOLDING STOVE.

SPECIFICATION forming part of Letters Patent No. 669,281, dated March 5,1901.

Application filed May 15. 1900.

To all whom it may concern.-

Be it known that I, FRANK SILES LANG, a citizen of the United States,residing at Helena, in thecounty of Lewis and Clarke and State ofMontana, have invented a new and useful Portable and Folding Stove, ofwhich the following is a specification.

My invention is an improved portable folding stove, the object of myinvention being to provide an exceedingly light, cheap, and simple stovewhich is adapted to be folded compactly for transportation or storagewhen notin use and is particularly adapted forcamp purposes for heating,cooking, and baking.

My invention consists in the peculiar construction and combination ofdevices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved portable folding stove, showing the same set up ready for use.Fig. 2 is a vertical longitudinal central sectional view of the same.Fig. 3 is a vertical transverse sectional view of the same, takenthrough the fire-box. Fig. 4 is a perspective view of the stove, showingthe same folded compactly and secured for transportation. Fig. 5 is avertical longitudinal central' sectional view of the same. Fig. 6 is avertical transverse sectional view of the same. Fig. 7 is a detailperspective view of the lower section of the stove-pipe. Fig. 8 is adetail sectional View of a portion of the stovepipe, showing the dampertherein. Fig. 9 is a detail elevation of the same.

The bottom of the stove is formed of a pan 1, made of sheet-iron orother suitable material, and in which is a false corrugated bottom 2,-ofsheet metal, and asbestos or other non-conducting filling 3 ispreferably interposed between the bottom of the pan and the saidcorrugated false bottom. The latter is riveted or otherwise suitablysecured in the bottom of the pan. Said pan 1 is provided at its endswith bails 4, of the form shown and having their end portions curved orbent, said end portions of the respective bails being curved or bent inopposite directions, and said bails are hinged under the bottom of thepan, as at 5, and when turned downward under the bottom of the pan, asshown in Figs. 1, 2, and 3, serve to support the stove at a Serial No.16,800- (No model.)

suitable elevation above the ground or floor or table on which it may belocated, and when turned upward over the ends of the pan, as shown inFigs. 4 and 5, said bails serve to secure the bottom of the stove to theother portions thereof when the stove is folded for transportation orstorage.

The top 6 of the stove is preferably made of sheet-steel, but may bemade of other suitable material and is provided with depending endflanges 7 and side flanges 8. The length and breadth of the top of thestove are something less than the corresponding dimensions of the panwhich forms the bottom of the stove, so that the top of the stove isadapted to fit within the pan bottom of the stove when the stove isknocked down or compactly folded and stowed. Said stove-top is providedwith the usual openings Sand plates 9 to cover said openings, and nearone end of the stove-top is an opening 10 for the insertion of the lowerend of a section 11 of stovepipe. The ends 11 12 of the body of thestove are hinged at their upper sides within the depending flanges 7 atthe ends of the stove-top, as at 13, and thereby the said ends 11 and 12are adapted to be folded inward under the top of the stove. The end 11is provided on its inner side with a sheet of corrugated iron or steel,as at 14, the same being riveted or otherwise secured to the end 11, anda filling of asbestos or other suitable material, as at 15,.isinterposed between the end 11 and the corrugated sheet 14:. The end 11is further provided with draft-openings 16 and pivoted plates 17 toclose or vary the size of said openings, and thereby regulate the draft,and the ends 11 and 12 are provided near their lower sides with hingedbails 18, which are adapted to be turned downward under and engage theflanges 19 at the ends of the pan-like bottom of the stove, as shown inFigs. 1 and 2, so as to secure the body of the stove on the bottomthereof when the stove is set up ready for use. The sides20 21 of thestove are hinged at their upper sides within the depending side flanges8 of the top of the stove, as at 22, and thereby the said sides areadapted to be folded inward under the top of the stove when the stove isfolded compactly, and the said sides 20 21 are provided at their endswith inturned flanges 23, which engage the ends 11 12 of the stove whenthe same is set up, as shown in Fig. 1. The side 21 of the stove isprovided with a door 24, through which fuel may e supplied, and with anoven-door 25. Said sides and ends of the stove may be made of sheet-ironor other suitable material.

The oven of the stove comprises the top and bottom plates 20 2'7 and theinner and outer end plales 28 29, respectively. said plates beingsecured together at the corners of the oven by hinges, as atv 30,whereby the top, bottom, and ends of the oven are articulated and thesame is adapted to be compactly folded. The front and rear sides of theoven are formed, respectively, by the door 25 and the side 20 of thestove, and the oven is suspended within the stove at one end thereof andat a suitable distance from the top, bottom, and end 12 by the links 3],which are pivotally connected to the under side of the top of the stoveand to the upper plate of the oven, as at 32, and thereby the saidlinks, while suspending the oven in such position within the stove as toadmit of a draft entirely around the oven from the fire-box formedbetween the end plate 28 of the oven and the end 11 of the stove, permitthe plate 26, forming the top of the oven, to be swung in contact withthe upper side of the stove when the stove is knocked down.. The end 28of the oven is covered on its outer side with a corrugated plate 33, anasbestos or other suitable nonconducting filling 34 being interposedbetween said end plate 28 and said corrugated plate 33, and thereby theend of the oven forming the inner side of the tire-box is prevented frombeing unduly heated.

The top of the stove, at a point between the openings 8, is reinforcedby a transverse plate 35, which is riveted to the under side thereof,and which plate forms the pivotal connection between the top of thestove and the link which suspends and supports the inner end of theoven, and the stove-top is further reinforced by a transversely-disposedplate 36, which is riveted to the under side of the stove at a pointbetween the opening 10 and the proximate opening 8.

The lower end of the stovepipe-section 11 is reduced on its front sideby a rabbet 37, thereby forming an opening in the front side of thestovepipe, at the lower end thereof, and when the stovepipe is insertedin the opening 10 the opening 38 in the front side of the pipe ispresented to the flue above the oven, so that the products of combustionmay readily escape through the stovepipe and the latter be securelyattached to the stove. The said stove pi pe-section is further reducedat its heel or lower end by a rabbet 39,which engages the oven at theupper corner thereof, as-shown in Fig. 2, and serves to prevent the ovenfrom swaying or swinging in the stove when-the latter is set up.

In the Stovepipe, on one side thereof, at a suitable point is made atransversely-disposed slit or narrow slot 40, which is curved, as

shown. A dam pet-41 is made from sheet-iron and is of suitable form andconcavo-convex in cross-Section to adapt the same to the conton r of thestovepipe and to fit snugly against the same when the damper is open.The said damper is formed integrally with the outer arm 42, which formsan extension thereof and projects through the curved slit or slot 40 inthe stovepipe. Hence the said arm is compressed between the sides of thesaid slit or slot, and owing to the curvature of the latter and therotundity of the stovepipe said pipe and said arm of the damper formcoacting springs which serve to maintain the damper in position eitherwhen opened or closed, as will be understood. When the damper is open,the same is disposed in close relation to one side of the stovepipe,entirely out of the way.

No claim is made herein to the Stovepipe having a curved slit or slot incombination with a dam perconstructed as herein described and fitted insaid slit or slot, as the same constitutes the subjectmatter of adivisional application for Letters Patent of the United States which Iam about to file.

Having thus described the invention, I claim-- 1. In a folding portablestove, the bails having the U-shaped end portions and pivotally attachedto the bottom of the stove at points within the edges thereof, andadapted to be folded under the same to serve as supportinglegs for thestove, said U-shaped end portions forming relatively broad supports forthe stove, and also adapted to clear the ends of the stove and be turnedupward to engage, overlap and lock the upper portion of the stove to thebottom thereof when the stove is folded, substantially as described.
